【问题描述】：

我使用Spring 和Hibernate 并使用Oracle 11g 作为数据库 我使用了JBoss 5。

我无法自动重新建立连接

我用c3p0-0.9.1.1.jar

这是我的应用程序中的配置：

<?xml version="1.0" encoding="UTF-8"?>

但我有这个错误：

我的应用程序使用以前的数据库配置可以正常工作，但我的问题是当我与我的应用程序有很多连接（超过 200 个用户）时出现错误，这就是我使用连接池的原因。

当我在服务器中出现此错误时，oracle 服务可以正常工作，因为我可以直接在数据库中执行查询。 只是问题出在我部署在 jboss 和 oracle 中的应用程序的连接之间

在_BaseRootDAO.java我有这个方法：

/**
 * Return a new Session object that must be closed when the work has been completed.
 * @return the active Session
 */
public Session getSession() {
    return getSession(
        getConfigurationFileName());
}

/**
 * Return a new Session object that must be closed when the work has been completed.
 * @param configFile the config file must match the meta attribute "config-file" in the hibernate mapping file
 * @return the active Session
 */
protected Session getSession(String configFile) {
    if (null != session && session.isOpen()) return session;
    else if (null != sessionFactory) {
        Session s = currentSession.get();
        if (null == s || !s.isOpen()) {
            s = sessionFactory.openSession();
            currentSession.set(s);
        }
        return s;
    }
    else {
        Session s = currentSession.get();
        if (null == s || !s.isOpen()) {
            s = getSessionFactory(configFile).openSession();
            currentSession.set(s);
        }
        return s;
    }
}

更新：

这是 Oracle 数据库中的当前设置

RESOURCE_NAME, CURRENT_UTILIZATION, MAX_UTILIZATION

sessions    93  156
enqueue_locks   81  149
enqueue_resources   18  52

我尝试使用最新版本的 c3p0

c3p0-0.9.5.2.jar 安装在 c3p0-0.9.1.1.jar

【问题讨论】：

    标签： java spring oracle hibernate jdbc


    【解决方案1】：

    什么对我有用：

    我的用例：
    我正在运行与 DB（Oracle 12c）的并行连接，以测试我是否从序列中获得不同的序列值。随着并行连接的增加，有一点我得到“ORA-12519，TNS：找不到合适的服务处理程序”

    经过数小时的故障排除后，什么有效：

     1. ALTER system SET processes=XXX SCOPE=SPFILE;

    （注意：逐渐增加 XXX（如 +200 左右），因为如果将其增加到过高的值，您将无法启动您的 Oracle 实例，因为它无法支持它!!)
    2. 提交;
    3. 重新启动数据库。
    （注意：不要忘记重新启动数据库，以使更改在 SPFILE 中生效。）
    4.最后查询看到我的变化，即limit_value：

    select resource_name, current_utilization, max_utilization, limit_value
from v$resource_limit
where resource_name = 'processes';

    【讨论】：

      【解决方案2】：

      好吧，让我们稍后再讨论 Oracle 侦听器/数据库配置的问题，并尝试简单的事情：
      你能检查一下jdbc url是否正确吗？在这种情况下，请注意 SID 和服务名称的差异：
      对于 SID

      <property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521:production"/>

      对于服务名称

      <property name="jdbcUrl" value="jdbc:oracle:thin:@localhost:1521/production"/>

      【讨论】：

      • 感谢您的回复，我的应用程序使用以前的数据库配置可以正常工作，但我的问题是当我与我的应用程序（超过 200 个用户）有很多连接时出现以前的错误，这就是我使用连接的原因游泳池
      • 现在这是有道理的。在这种情况下，可能有两件事：连接池配置中的一些问题，或者连接数太大。第二期请看stackoverflow.com/a/9561838/1453045
      【解决方案3】：

      您可以尝试使用“通用连接池”，这是一个用于测试的 Java 连接池。有关详细信息，请参阅博客“UCP with Hibernate”。
